In a clinical trial of 2150 subjects treated with a certain drug, 30 reported headaches. In a control group of 1643 subjects given a placebo, 26 reported headaches. Denoting the proportion of headaches in the treatment group by p, and denoting the proportion of headaches in the control (placebo) group by pe the relative risk is p/p The relative risk is a measure of the strength of the effect of the drug treatment. Another such measure is the odds ratio, which is the ratio of the odds in favor of a headache for the Pi/ (1-Pi) treatment aroun to the odds in favor of a headache for the control (nlacebo) aroup found hy evaluating - The relative Find the relative risk for the headache data. The relative risk = (Round to three decimal places as needed.) Enter your answer in the answer box and then click Check Answer.
